Abstract
An electrolytic capacitor includes a capacitor element and an electrolyte solution. The capacitor element includes an anode foil, a cathode foil that is opposite to the anode foil, and a conductive polymer layer that is disposed between the anode foil and the cathode foil. An inorganic layer including at least one selected from the group consisting of conductive carbon, titanium, and nickel is disposed on the cathode foil. The conductive polymer layer includes a conductive polymer. A proportion of water in the electrolyte solution ranges from 0.1% by mass to 6.0% by mass, inclusive.
